More information is needed: Is this a 2" x 6" 10 feet in length? Is this for a floor, deck, roof or what? Is this supported on both ends or cantilevered? Is this for interior or exterior?
Yes, a W-8X18 will carry the weight of a basement load wall 2X6 over a 200 feet span.
It depends on the type of beam, the material, whether it is a bridge span or cantilever, the allowable deflection and safety margin needed. We need a lot more data on the application.
That depends on many other factors. What is the beam material? Is the load a point load concentrated in one spot, or is it uniform across the total span? Specing beams is something that should be left up to a qualified person.
Hi, I am only an undergrad civil engineer so feel free to correct me if I am wrong, but I will try to help! Say we are dealing here with a steel beam, spanning across a ceiling, and the load applied to it is the floor above. Let's presume it is supporting 2 loads, the concrete slab above it (dead load) and the service load (live load), i.e. people walking over the floor and hence varying. We need to estimate the area of floor the beam is supporting, so obviously this will be in m^2, and we also need to depth. We also need the characteristic service load for our type of building, and this can be found in a book such as the Metric Handbook (a must have for engineers!!) We then take the total area value to British Standards tables, which will give us a self weight of the concrete for a certain depth and a certain characteristic service load. It will also tell us the effective span of the floor. We then add together the dead load and live load, for the total load on the beam, so: applied load = (total area x concrete self weight) + (total area x characteristic service load) This should give you quite a large value with real buildings. UDLs are measured in N/m or kN/m, and so finally we just need to divide the total load by the span of the beam in metres. Also, not all of the load will be on the beam, some will be applied to the supporting structures, so you can assume that only somewhere around half of the final load is the UDL over the span of the beam. Hope this helps, Luke
The strength, S, of the beam is Mc/I where M = max moment to fail = PL/4 for load concentrated in the middle of the beam or WL/8 for uniformly distributed load. Here P is the concentrated load, W = distributed load, c = distance to outer fiber from neutral axis and I the area moment of inertia of the beam. L = length Solving for load maximum, P = 4IS/Lc for concentrated center load W = 8IS/Lc for distributed load

Its depends on location and type of towers. Supposed the transmission line is erected at hill area and second line is erected in desert area and third one in forest area. Then the allowable value of weight span and wind span ratio in transmission line will different. Also this ratio will depends on types of tower . Like the value is different in 132KV, 220KV , 400KV and 765KV.

Several factors affect the allowable spans. Each manufacturer of laminated beams have specific load limits and allowable spans. The total load that is going to be placed on the beam should also be factored into the equation. Heavier loads will require more support, reducing the maximum span allowed. If the manufacturer cannot be determined, then local building codes should be consulted. Building inspectors can be contacted to help you determine the appropriate span.
The design, the load, and its resistance to weather. The biggest though, is the way it holds up weight. This really effects the maxium span. The biggest difference is the span of the bridges.

How far can 1 by 6 span without support
The answer to this question depends upon several criteria: 1. The span of the floor framing members 2. The 'on center' spacing of the floor framing members 3. The nominal dimension of the floor framing members (2x12 etc.) 4. The grade and species of the wood 5. Size and location of any holes or notches in the framing members A typical residential floor designed for a 10 psf Dead Load, 40 psf Live Load and a deflection criteria of L/360 (mid span deflection limited to L in inches/360): 2x12 joists at 16" on center spacing, Spruce-Pine-Fir #2, will have an allowable max span of 17'-10". 2x12 joists at 16" on center spacing, Southern Pine #2, will have an allowable max span of 18'-10". 2x10 joists at 16" on center spacing, Spruce-Pine-Fir #2, will have an allowable max span of 15'-5". Random thoughts: Thinset ceramic tile with mortar will add about 10 psf dead laod. Location of very heavy objects can be critical when determining a floors capacity.
If you askabout aluminum Profiles the allowable deflection less than 1/200 of the span and not more than 8mm (this specs to avoid breaking glass)
That depends on many other factors. What is the beam material? Is the load a point load concentrated in one spot, or is it uniform across the total span? Specing beams is something that should be left up to a qualified person.
The answer is not formulatic. There will be a parabolic shape from the dead load and a discontinuity at the point load.
38 feet longIt is not possible to give a definite answer without more detail. The construction and type of roof will determine the load (weight) bearing on the beam, and factors such as wind load and earthquake load, and the way the roof bears on the beam (truss/point load/distributed load) will all affect the sizing.
